I have two baby bettas that are only about an inch long. They are both in fairly small "bowls" right now. I have a gallon 1/2 tank and a 2 gallon tank set up as their permanent homes. How big should these babies be before I move them into the bigger tanks?
In the two gallon I also have ghost shrimp swimming around in it currently, do I need to worry about the little shrimp picking on my baby betta?
Last questions, the two gallon tank temperature is always between 76 and 78 degrees, is this too hot for the betta?
Thanks for the help!

Those tanks would be just fine with some more plants and hidey places. The baby bettas are very easily stressed out, so the more cover the better. I realized with mine that they really like Java Moss, it gives a huge ammount of cover for cheap. lol!
